During the generation period, a first driving means performs an automatic recording level control operation, and is triggered by a signal in which the output voltage of the recording amplifier exceeds the operation level, and stops the automatic recording level control operation for a predetermined period, and also stops the automatic recording level control operation for a predetermined period. A second driving means for automatically controlling the recording level during a period in which the output voltage of the recording amplifier exceeds the level and after the predetermined period has elapsed. circuit.
